EDWARD J. STEPHENS, OF PAIVTUCKEI, RHODE ISLAND.

YARN-PRINTING MACHINE.

EPECIFICATION forming part of Letters Patent No. 338,314, dated March23, 1886.

Application filed October 29,1885. Serial No. 181,234. (No model.)

.To all whom it may concern:

Be it known that I, EDWARD J. STEPHENS, of the town of Pawtucket, countyof Providence, and State of Rhode Island, have invented anew and usefulImprovement in Yarn- Printing Machines; and I do hereby declare that thefollowing specification, together with the accompanying drawings, is adescription sufficiently clear to enable any one skilled in mechanics tomake and use the same.

In the drawings, Figure 1 represents a side View of the machine; Fig. 2,a front view.

The purpose and object of my invention is the production of a machine toprint yarns or fabrics in consecutive colors without variation orinequalityin color or figure, perfectly automatic, and with entirecertainty. This endis achieved in a machine built as described in thisspecification, and illustrated in the drawings herewith.

In Fig. 1, a is the frame of machine.

b is the driving-pulley; c, a shaft on which is the printing-drum d, theface of which is shown in Fig. 2. This shaft is driven by gear 6 fromsmall gear 6', which is on shaft with driving-pulley b.

fff are ink-rolls, supported by yielding bearings g.

h h h are doctors for scraping all superfluous ink from rollers.

12 andj are plain rolls for keeping even ten sion on yarn.

kis yarn from beam or spool,passing between printing-drum d andink-rollers f, and led away to dry-room at Z.

The ink-rollers are revolved by means of gears from gear 6, and thehexagonal cams m, forming part of these gears, operate by being incontact with a flange, 6, made with or connected with gear 6, said camsbeing so arranged as to allow the ink-rollerf to come in contact withany desired points on the print ing-drum d. The inking-rolls f f f havetheir axles set in bearings set in springs n, thus allowing thevibratory motion caused by the cams.

In the operation of the machine, which is driven by a belt from pulleyb, the several color-rollers will ink those parts of theprinting-cylinder which are allowed to come in contact with them by thecams, and the yarn or fabric passing between the printing and inkingrolls receives theimpression and color desired. Any number of colors canbe printed by increasing or decreasing the number of ink-rolls, and anykind of pattern by substituting a different printingroll.

Hitherto machines have been patented and used by myself (see LettersPatentofthe United States No. 83,103, dated October 13, 1868) whichprinted the yarn by passing between two printing-rollers, eachprinting-roll receiving the ink from independent ink-rolls, thealternate motion of which was caused by cutting the gear-teeth to avariable deptlnthus allowing it to approach and retire from theprinting-roll. In my improved machine I ob tain this motion by means ofcams m-a more simple. and efiective movement.

By means of this improved machine more distinct colors are obtained andwith less blending of adjacent ones than by the old process.

Therefore what I claim as my invention, and desire to secure by LettersPatent, is

1. A yarn or fabric printing machine using several colors, consisting offrame a, printingdrum d, ink-rolls f, and yielding bearings 9,controlled by cams m, combined substantially as described, and for thepurpose specified.

2. In a yarn or fabric printing machine, the combination of the fluteddrum and ink-roll,as described, to print by. pressing the ink-rollagainst the yarn or fabric while passing around the revolving fluteddrum, substantially as described.
